Application filed August 9, 1912. Serial No. 714,263.

To all whom it may concern Be it known that I, ALBERT Gsono Koiccir LIN, a citizen of the Swiss Republic, and resident of Basel, Switzerland, have invented new and useful Improvements in Thread-Moistening Apparatus for Textile- Machines, of which the following is a full, clear, and exact specification.

The resent invention relates to a device for moistening the threads on looms.

In spinning and weaving mills. this niois tening or damping of the threads has hitherto been effected by charging the air in the room with'moisture by means of water distributing devices or the like attached to the ceiling so arranged as to atomize or divide the liquid prior to its entrance into the room into a finely divided state. The disadvantage of this arrangement in the first place is that the entire room is charged with moisture which unnecessary and in some cases objectionable, and furthermore if the distributor fails to act for any reason there is danger of insufficient division of the water, so that water drops down into the room and on to the machines in the room with consequent damage and inconvenience. In other arrangements for the same purpose, a mixture of air and water is forced.

upon the threads in a nearly horizontal direction, or from above, or from one side, by sprayers, spray producers, nozzles and the like, in others the threads to be damped pass over perforated moistening tubes or the like or are moistened by spraying brushes and so on, but in all these cases the damping fluid may convey water drops which have no time for separating themselves from the air before meeting with the threads.

According to the present invention a vertical blast or breeze of moistened air is supplied from below to the underside of the warp threads of a loom by means of a large opening or outlet arranged below the warp of the loom, said opening being provided if desired with closing means positively connected to the stop lever of the loom, so that the stopping of the loom produces at the same time the closing of the moistened air delivery opening or outlet. The improved method of dumping the threads from below enables the moistened air to be delivered in a blast or breeze rising freely underneath the warp to be treated,

so that any heavy drops of water fall dow 1 by their own weight and are not supplie to the threads, while the blast of moistened air distributes itself regularly and with substantially the same moistening strength over the whole breadth of the warp.

In the accompanying drawings the invention is illustrated by way of example as applied to a number of looms in a weaving room.

Figure l is a lan view of a weaving room showing a num er of looms with the invention applied thereto; Fig. 2 being a sectional view in side elevation of the room and looms illustrated in Fig. 1 and showin one method of controlling the supply 0 moistened air to the threads.

Referring now to the drawings the room a is shown provided with a covered-in conduit or channel b located adjacent to one of the Walls of the room and a pipe 0 through which water is forced under pressure by a pump d"from a reservoir 0. Transversely to the pipe 0 are arranged a number of blastpipes 7 each of .which extends under a row of looms w and is provided underneath the warp of each loom, with an upwardly directed large opening or outlet 9. At the inlet of each pipe f open to the conduit 1), there is arranged on the water pipe 0 a. nozzle' h projectin within the opening of the adjacent end 0 said pipe f, said nozzle it being so arranged that the liquid issuing from the nozzle into the pipe f operates as an injector to withdraw air from the conduitb and force the same into the blastpipe'' 7, the moistened air thus obtained issuing under slight pressure from the openings 9 and being directly supplied in the form of a blast onbrecze to the warp of the looms. The air may be obtained either through shaft openings 11 arranged in the interior of the room, or through shaft openings is located in the exterior, both of these shaft openings z', 70 being connected to the channel b and preferably provided with controlling devices for regulating theamount of air supplied. The openings 9 for the outlet of the moistened air are also provided with closing or shutting devices m for controlling the passage of the fluid to the threads on the loom; in the arrangement shown in Fig. 2 these regulating devices on are connected to the usual knock-off lever of the loom so as to be closed automatically when the loom is put out of operation.

Instead of providing injecting nozzles as above described, the damp air can also be supplied to the underside of the threads of the looms by means'of a fan or in any other suitable manner. It will be understood therefore that the invention is not limited to the particular arrangement here in described and illustrated and various modifications may be made Without exceed ing the scope of the invention.

dVhat I claimis:

1. A moistening apparatus for looms comprising a plurality of distributing channels each extending beneath a row of looms; a blast pipe in each of said channels having an outlet beneath each loom of the row and open at one end; a supply channel communicating with all of said distributing channels at the open ends of said blast pipes; a water supply pipe in said supply channel having a discharge nozzle opposite the open mouth of each of said blast pipes; an air flue for each of said blast pipes, said air flue opening at one end to the outer air and at the inn ,er end in the neighborhood of the open end of its corresponding blast pipe; and a valve beneath each loom adapted to govern the outlet from the blast pipe to the loom.

2. A moistening apparatus for looms coniprisinga plurality of blast pipes each extending beneath a row of looms and having an outlet beneath each loom of the row and open at one end a water supply pipe having a discharge nozzle for each of said blast pipes; and an air flue for each of said blast pipes, said air flue opening at one end to the outer air and at the inner end in the neighborhood of the open end of its corresponding blast pipe.

3. A moistening apparatus for looms comprising a plurality of blast pipes, each ex tending beneath a row of looms and having an outlet beneath each loom of the row and open at one end; and a water supply pipe having a discharge nozzle for each of said blast pipes.

4. A moistening apparatus for looms com prising a blast pipe extending beneath a row of loom's and having an opening beneath each loom and ilpen at one end; a water supply pipe having a discharge nozzle for said blast pipe; and an air fine opening at one end to the outer air and at the inner end in the said blast pipe.

A moistening apparatus for looms comprising a blast pipe extending beneath a row of looms and having an outlet beneath each loom and open at one end; and a Water sup ply pipe ha ring a discharge nozzle for said blast npe.

6. moistcning apparatus for looms comprising a blast pipe having an opening beneath a loom and. open at one end; a water supply pipe having a di charge nozzle for saidblast pipe; and an air flue opening at one end to the outer air and at the inner end in the neighborhood of the open mouth of said blast pipe.

7. A moistening apparatus for looms com prising a. blast pipe having an outlet beneath a loom and open at one end, and a water supply pipe having a discharge nozzle for said blast pipe.

In witness whereof I have hereunto signed my name this 6th day of July 1912, in the presence of two subscribing Witnesses.
